What Is an Age Calculator?
An age calculator is an online utility that calculates the amount of time between a date of birth and the current date.
Instead of estimating age from the birth year alone, the ToolStrive Age Calculator uses the complete date of birth to display age in years, months and days.
How to Use the Age Calculator
- Select your date of birth.
- Click the Calculate Age button.
- View your age in years, months and days.
- Check additional information such as total months, weeks and days.
- View the date and countdown for your next birthday.
How Is Age Calculated?
Age is calculated by comparing the selected date of birth with today's date.
The calculation first determines the number of complete years. It then calculates the remaining complete months and days between the most recent age milestone and the current date.
This produces a result such as 25 years, 4 months and 12 days instead of displaying only the number of completed years.
